Remitano and rineck or rinec...

I watch a comedy about remitano and the mining rineck or what they call it I don't know the spelling.

I am not about the comedy because we can not follow comedy, what they are advertising can be risky that is why I am here to ask you. What is mining rineck?

I check coin market cap and coingecko I did not see it.
